RADIATOR.

Specification of Letters Patent. Patented Apr. 11 1911. Applicationfiled November 2-7, 1908.

Serial No. 464,769.

To all whom it m c y concern:

Be'it known that l, FRANCIS 1. (human, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented a..new and useful linprovemcnt iirfiadiators, of which thefollowing is a specification.

" This invention relate to radiators for use in heating systems, andmore particularly to steam radiators of that kind which are composed ofa plurality of radiating sections having controlling means for theheating fluid which permit any one or more of said sections to be usediinlependently of the other section, or sections, for regulating theheat of the radiator as desired.

The objects of the invent-ion are to produce a practical. and desiablesectional radiator of this sort which is of simple construction, suchthat itcan be economically manufactured and installed; also to make aradiator of a plurality of independently controlled sections which areconstructed and arranged longitudinally side by side in such manner thatthe radiator, as a whole, will resemble L the ordinary radiator built upof a series of transverse communicating loops or sections and will havea large radiating surface; also to improve sectional radiators of thistype in the respects hereinafter described and set forth in the claims.

In the accompanying drawings: Figure 1 isa side elevation of a radiatorpartly in section embodying the invention. .Fig. 2 is an elevation ofone end thereof. Fig. 3 is an elevation of the other end thereof.showing the airvalveand connections. Fig. 4- is a transverse sectionalelevation thereof on line 4-4, Fig. 1.- Fig. 5 is an end view of thesections separated.

Like letters of reference refer to like parts in the several figures.

The radiator illustrated in the drawings is provided withconnections foruse in a single pipe steam heating system. The improvements are not,however, restricted in application to radiators for singlepipe steamsystems, and the sectional construction hereinafter describedisappli'cable to radiators for use in other kinds of steam and hot waterheating systems.

- The. radiator is preferably composedof' three longitudinal sections;two outer tions A A, and an intermediate or middle section arrangedbetween the outer scc-.

which approach each other 'ordinary radiator of like size.

with upright radiating loops. columns or 6 portions a which areseparated by intervenmg a1r clrculating spaces and communicate at theirupper and lower ends through hollow connecting portions 0. In the caseof ng radiators it is desirable, from a manufacturing standpoint, tojoin a plurality of the short sections described to form each longsection of the radiato instead of making each section in one piece fromend to end of the radiator. also preferably. though not necessarily.formed like the outer sections, with spaced upright radiatingloops-columns or portions communicating at their tops and bottoms.

The outer sections A A are provided with supporting feet or portions butthe intermcdiate section is secured to and supported ontrrely by theouter sections above the floor and has no feet. Preferably the outersections are taller than the intermediate section 30 B andhave top andbottom extensions a above and below the intermediate section so as topractically inclose the intermediate section except at its ends. withsmall'external lugs I), Fig. 5, adapted to bear against the inner sidesof the outer sections, the adjoining faces of the sections can be heldout of contact with each other when the sections are assembled, thusform 0 ing additional narrow air circulating spaces J) between the outerand intermediate sec tions The provision of the lugs also enablessections to be more readily fitted together,

as the lugs can be quickly cut down as may be required to allow forirregularities in the sections which would otherwise interfere with-theproper assembling of the sections. lVhen the three sections thus formedare assembled, the radiator as a whole is very similar in shape andgeneral appearance to the ordinary radiator made up of transverse loopsor sections, and it has a radiating surface of substantially the samearea as the mediate section is thus confined and supported in place bythe outer sections.

While three sections constructed and arranged as described arepreferred, the radiator could conslst of onlv two or more 1 Theintermediate section is 70 By making the intermediate section 35 Theintertseetionab at, th ends as. oe ema than three sections, but whatevernumber of sections is employed the outer sections are preferablyconstructed sul'istantially as described so as to give the radiatorsubstantially the same external appearance as the ordinary radiator withtransverse loops.

C represents a steam supply pipe which is located at one end of theradiator and connects by branches (1 c r. with the upper portions of theseveral sections A A ll, and by branches (Z (Z (Z with the lowerportions ot' the sections. The steam pipe is provided with the usualcut-ol't' valve c and each of the upper branch pipes c c is providedwith a separate valve 1) whereby the steam can be admitted to any one ormore of the sections independently of the other section, or sections. Acheck valve F is provided in each of the lower branch pipes (Z d Grepresents an ordinary automatic air valve located at the opposite endot'ihe radiator and connected with the several sections by branchpipes-g controlled by hand valves A seliarate air valve 'lor eachsection could be used. it preferred. ll| -l0illi ol' the single valvehaving the separate connections to the several sections.

\V'hen any section is to be heated the valve E therefor-is opened toallow st'eai'n to enter the section, The check valves F for the othersect-ions prevent the steam from entering them at the bottom so long asthe supply valves E for such sections are' closed, but the check valvespermit-the condensation to flow from the sections back into the steampipe, Thus any one or more of the sections may be heated so that theradiation is under control and capable of regulation.

The described steam connections are suchas would be usedin a singlep'ipe heating system, but itshou'ld be understood that the radiatorwould be diti'erently piped for use in otl 'eiidieaiting systems, andthe described p nstruction can be used with appropriate connections inditi'erent kinds of ste-a'n'i heating systems and also in'ltot waterheatieg systems. 'lhc- Iectqons ot the radiator are independentof ea d1other and diseoimected except by ons for the heating fluid and air f ;thrat-liator, and either section a'fntbe used alone, or the outer sectionsused witlioiit thb intermediate section or Hrt tioiis, asfacomplete-radiator.
